Titanium is a fascinating metal that promises high durability, strength, and corrosion resistance. While several grades of titanium are available in the market, ASTM B348 Gr 2 Plate stands out as one of the most widely used varieties. This blog post will help you understand the composition, physical and mechanical properties, uses, and heat treatment of titanium grade 2 sheet plates. Whether you work in the manufacturing, aerospace, or medical industry, you will find this information helpful in optimizing your processes and choosing the right titanium grade for your specific application.
Titanium Grade 2 Sheet Plate Composition
ASME SB 265 sheets comprises 99.2% pure titanium, with small amounts of iron and oxygen included. Ti Alloy Gr 2 grade is known for its high ductility, excellent corrosion resistance, and weldability. The low concentration of interstitial elements reduces the risk of hydrogen embrittlement and ensures that the ASTM B348 Gr 2 Plate can withstand high-temperature exposure.
Titanium Gr2 Sheet Plate Physical Properties
UNS R50400 Sheet plate has a density of 4.51 g/cm3, about half the sheet’s density. This property makes Gr 2 Titanium Sheets lightweight and ideal for high-strength and low-weight applications. The melting point of this grade is 1668 Celsius, and it has a thermal conductivity of 20.6 W/mK. Additionally, Titanium Plate Grade 2 is non-magnetic, which makes it useful in industries where magnetic interference is a concern.

Titanium Gr.2 Sheets & Plates Uses
UNS R50400 sheet plate has numerous applications in different industries. It is commonly used in aerospace, marine, and chemical processing industries due to its high strength-to-weight ratio and corrosion resistance properties. It is also used in medical devices such as dental implants, artificial joints, and pacemakers due to its biocompatibility and low toxicity. Additionally, Ti Alloy Gr 2 Plates is used in heat exchangers, valves, and piping systems.
ASTM B265 Sheet Plates Heat Treatment
Ti Alloy Gr 2 Sheets can be heat treated to improve its mechanical properties. Heat treatment involves heating the material to a specific temperature and holding it for a certain duration before cooling it down. The most common heat treatment method is annealing, which involves heating the material to 704 degrees Celsius and holding it for up to two hours before cooling it down. This process increases flexibility and reduces the residual stress in the material, making it easier to machine.
Ti Alloy Gr 2 Sheet Plate Corrosion Resistance
One of the standout features of titanium grade 2 sheet plate is its corrosion resistance. UNS R50400 Plates is highly resistant to attack in alkaline, acidic, and oxidizing environments, making it an excellent choice for corrosive environments. UNS R50400 Sheets is also resistant to pitting and crevice corrosion, which are common types of corrosion that occur in metals exposed to saltwater and chloride environments.
